Locally, when barbers were allowed to use a straight razor to shave you with, I recall barbers using a 5/8 full hollow round point to shave their clients with. It was all that was needed to give clients a safe, comfortable and close shave. I think a 5/8 round point shave ready razor of any grind is a good starting point for a beginner today. It's all you need to get a good shave.
